5 Std 3

6 DO NOW: 1. Balance these equations: a. ___ HgO ---> ___Hg + ___O 2 b. ___ Zn + ___ HCl --> ___ ZnCl 2 ___ H 2 1 2 Spotlight.exe Coefficient - the number in front of each element/compound in an equation

7 Reactants LEFT Products RIGHT Cu (s) + AgNO 3 (aq) -----> Ag (s) + Cu(NO 3 ) 2 (aq) The LAW of CONSERVATION OF MASS requires that we balance chemical equations Spotlight.exe

8 Link for video showing reaction of copper wire (Cu) with silver nitrate solution ( AgNO 3 ) http://www.mrwiggersci.com/chem/Smart-Board-Activities/Ch10-Chemical-Reactions/Cu-plus-AgNO3-vid.mpg Cu (s) + AgNO 3 (aq) -----> Ag (s) + Cu(NO 3 ) 2 (aq) link 1 2 Spotlight.exe If watching at home, click here to see vide

9 Answer 2 H 2 + O 2 2H 2 O balancing chemical equations.avi Work through this sample together, or click on the video file below to watch, listen, and learn how to balance a chemical equation. Video Tutorial __H 2 +__O 2 ---> __H 2 O 1 2

10 Answer C + 2Cl 2 CCl 4 Balance the following equation. __C + __Cl 2 ---> __CCl 4 1 2

11 Answer C aCO 3 CaO + CO 2 __CaCO 3 ---> __CaO + __CO 2 1 2

12 __H 2 + __Cl 2 ---> __HCl __H 2 O 2 ---> __H 2 O + __O 2 __Na + __F 2 ---> __NaF __KClO 3 ---> __KCl + __O 2 __P + __O 2 ---> __P 4 O 10 1. 2. 3. 4. 5. DIRECTIONS: Copy these equations on the paper you will be turning in. Balance each equation on your own.
